Application filed J uly 20, 1918. Serial No. 245,888.

To all whom it may concern:

Be it known that I, MIoHAEL DORION, a citizen of the United States,residing at Rumford, in the county of Oxford and State of Maine, haveinvented new and useful Improvements in Window-Locking Devices, of whichthe following is a specification.

This invention relates to a window locking device and more particularlyto means for locking an upper sash, a lower sash, or for locking bothsashes at one time in open position. The device is also useful insecuring a closed window sash when it is desired to employ it for thatpurpose.

A further object is to rovide a device adapted to be applied to t eupper edge of the lower sash after the latter has been raised, or afterthe upper sash has been lowered, said device engaging the space betweenthe window stiles and including elements designed to positively engageeach sash.

A further object is to provide a device including a metallic frame ormounting member in which a plunger or the like is carried, said plungerbeing operated by an eccentric element controlled by a lever engaging asegment, the plunger carrying a head for positively engaging one of thesash members.

With the foregoing and other objects in View the invention consists inthe novel construction, combination, and arrangement of elementshereinafter described and claimed.

In the drawings, 7

Figure 1 is a to plan view showing the device in position ]11St abovethe lower sash.

Fig. 2 is an edge view, in elevation.

Fig. 3 is a horizontal section.

FFig. 4 is a section on the line 44 of Fig. 5 is a bottom plan view of aportion of the structure of Fig. 1 and showing especially a cam memberengaging one sash in the manner shown in dotted lines in Fig. 1.

The frame 10 formed of metal carries on one side thereof an oflt'set 12provided with a serrated edge 13 engaging the stile of the window frame.The element 10 is provided with a channel 14 within which the 'operative members are mounted, one end of the channel being open as shown at15 and the other end terminating at or about the point 16.

A pin 17 extends through the frame 10 and serves to mount on the endthereof outside of said frame a cam member 18 engaging the frame of oneof the sash members when the device is in operative position. This camis provided with an operative arm 19.

The'pin 17 also serves to mount a pivoted arm or lever 20 by means ofwhich a plunger engaging the other sash member is operated. This plungeris designated 21 and is provided with a head 22 for directly engagingthe sash element last named. Guiding pins 24 are carried by head 22 andoperate within bores 25 in the element 10.

The plunger 21 is connected with an extension 27, or is formed with suchextension, the latter receiving a transverse pin 28 operating incccentrically formed slots 30 and 31 in the enlarged portion 32 of theelement 20. The extension mentioned projects into a channel 34 in theedge of the enlarged portion. The curved slots are eccentric withreference to the pin, and upon the movement of arm 20 the plunger ismoved inwardly or outwardly with reference to element 10.

Arm 20 is provided with slot 38 and through this slot there extends asegmental rack 39, the teeth of which are engaged by a pawl 40 normallyheld in operative position by a spring 41 encircling a pin 42constituting a guiding element for the pawl. Pin 42 operates in aperture42, and is provided with a head retaining it in operative connectionwith the pawl. The element last named is pivotally mounted by means of astaple 40 the yoke portion of which passes through the body of the pawl.

What is claimed is:

In a device of the classdescribed, a frame provided with a channelextending longitudinally thereof, an offset portion carried by the frameand adapted to engage a window stile, a plunger mounted within the frameand movable in a direction longitudinally thereof, a pivotally mountedarm 10- 'eated within the channel and provided with an enlarged portionhaving a slot extending partially around the edge thereof, one end saidpin extending mounted member carried by an outer end 10 of the pin, saidmember last named and the aforesaid plunger being positioned topositively engage respectively the upper and l lower: sashmemb'ers of aWindow.
